Definitions
- the present disclosure relates generally to electrosurgery and electrosurgical systems and apparatuses, and more particularly, to an electrosurgical apparatus with a retractable blade for use in cold plasma applications, electrosurgical cutting and mechanical cutting.
- Electrosurgical instruments generally comprise “monopolar” devices or “bipolar” devices.
- Monopolar devices comprise an active electrode on the electrosurgical instrument with a return electrode attached to the patient.
- the electrosurgical energy flows through the active electrode on the instrument through the patient's body to the return electrode.
- Such monopolar devices are effective in surgical procedures where cutting and coagulation of tissue are required and where stray electrical currents do not pose a substantial risk to the patient.
- Bipolar devices comprise an active electrode and a return electrode on the surgical instrument.
- electrosurgical energy flows through the active electrode to the tissue of a patient through a short distance through the tissue to the return electrode.
- the electrosurgical effects are substantially localized to a small area of tissue that is disposed between the two electrodes on the surgical instrument.
- Bipolar electrosurgical devices have been found to be useful with surgical procedures where stray electrical currents may pose a hazard to the patient or where other procedural concerns require close proximity of the active and return electrodes. Surgical operations involving bipolar electrosurgery often require methods and procedures that differ substantially from the methods and procedures involving monopolar electrosurgery.
- Gas plasma is an ionized gas capable of conducting electrical energy. Plasmas are used in surgical devices to conduct electrosurgical energy to a patient. The plasma conducts the energy by providing a pathway of relatively low electrical resistance. The electrosurgical energy will follow through the plasma to cut, coagulate, desiccate, or fulgurate blood or tissue of the patient. There is no physical contact required between an electrode and the tissue treated.
- Electrosurgical systems that do not incorporate a source of regulated gas can ionize the ambient air between the active electrode and the patient.
- the plasma that is thereby created will conduct the electrosurgical energy to the patient, although the plasma arc will typically appear more spatially dispersed compared with systems that have a regulated flow of ionizable gas.
- Atmospheric pressure discharge cold plasma applicators have found use in a variety of applications including surface sterilization, hemostasis, and ablation of tumors.
- the process can be relatively slow, generate large volumes of noxious smoke with vaporized and charred tissue, and may cause collateral damage to surrounding healthy tissue when high power electrosurgical energy is used.
- Precision accuracy can also be a problem, due to the width of the plasma beam.
- the present disclosure relates to an electrosurgical apparatus with a retractable blade for use in cold plasma applications, electrosurgical cutting, electrosurgical coagulation and mechanical cutting.
- the blade When the blade is retracted within the electrosurgical apparatus, it is electrically energized while an inert gas flows over it, producing a cold plasma discharge. In the de-energized state, the blade is advanced and used as a traditional surgical blade making contact with tissue to achieve mechanical cutting. Additionally, the blade may be advanced and used while both electrically energized and with inert gas flow. In this mode, the apparatus may be employed for electrosurgical cutting or coagulation.
- an electrosurgical apparatus includes a housing having a passage extending therethrough, the housing having a proximal end and a distal end; an electrically conducting tube having a proximal end and a distal end, the electrically conducting tube being disposed in the passage of the housing; an insulating outer tube having a proximal end and a distal end, the outer tube disposed around the electrically conducting tube with the proximal end of the outer tube coupled to the distal end of the housing, the electrically conducting tube being movable along a longitudinal axis of the housing and outer tube; an electrically conducting blade coupled to the distal end of the electrically conducting tube, and a transformer assembly disposed on the proximal end of the housing, the transformer assembly including a first transformer and a first switch for selectively coupling the first transformer and an external second transformer to the electrically conducting tube for providing electrosurgical energy thereto.
- the electrosurgical apparatus further includes a first slider member coupled to the electrically conducting tube for moving the electrically conducting tube thereby extending and retracting the blade about the distal end of the outer tube, the first slider member being accessible on the housing.
- the electrosurgical apparatus includes a second slider member coupled to the switch and configured to operate the switch, the second slider member being accessible on the housing.
- the first transformer is a step-up transformer and is configured to receive electrosurgical energy at a first predetermined value and the external second transformer is configured to provide electrosurgical energy to the electrically conducting tube at a second predetermined value.
- the electrosurgical apparatus includes a plurality of buttons configured to affect at least one electrosurgical mode based on a position of the first switch.
- the electrosurgical apparatus includes a second switch configured to determine a position of the blade and generate a signal indicating the position, the signal being transmitted to an electrosurgical generator.
- the proximal end of the electrically conducting tube includes a connector for coupling to a gas source to enable gas to flow through the electrically conducting tube over the blade.
- an electrosurgical apparatus including an electrosurgical generator coupled to an electrical power supply configured to generate electrosurgical energy, the electrosurgical generator including a step-down transformer coupled to the electrical power source and a first step-up transformer coupled to an output of the step-down transformer; and a handpiece including: a housing having a passage extending therethrough, the housing having a proximal end and a distal end; an electrically conducting tube having a proximal end and a distal end, the electrically conducting tube being disposed in the passage of the housing; an insulating outer tube having a proximal end and a distal end, the outer tube disposed around the electrically conducting tube with the proximal end of the outer tube coupled to the distal end of the housing, the electrically conducting tube being movable along a longitudinal axis of the housing and outer tube; an electrically conducting blade coupled to the distal end of the electrically conducting tube, and a transformer assembly disposed on the proximal end of the housing, the transformer assembly

If the output is not isolated, but referenced to “earth”, current can flow to areas with ground potential. If the contact surface of these areas and the patient is relatively small, an undesirable burning can occur.

- a current limiting capacitor 25 is provided in series with the electrode 28 to limit the amount of current being delivery to the patient 20 .
- the return path to the electrosurgical generator 12 is through the tissue and body fluid of the patient 20 , the conductor plate or support member 22 and a return conductor 32 (collectively return electrode) to the secondary of the transformer 24 to complete the isolated, floating potential circuit.
- the electrosurgical generator 12 comprises an isolated non-floating potential not referenced to any potential.
- the plasma current flow back to the electrosurgical generator 12 is through the tissue and body fluid and the patient 20 . From there, the return current circuit is completed through the combined external capacitance to the plasma generator handpiece 26 , surgeon and through displacement current.
- the capacitance is determined, among other things, by the physical size of the patient 20 .
- Such an electrosurgical apparatus and generator are described in commonly owned U.S. Pat. No. 7,316,682 to Konesky, the contents of which are hereby incorporated by reference in its entirety.

- the housing 102 includes a right side housing 110 and left side housing 112 , and further includes provisions for a button 114 and slider 116 .

The cutting speed is considerably faster, with less mechanical cutting resistance as compared to when the knife blade is not electrically energized, i.e., the mechanical cutting mode. Hemostasis is also affected during this process.
